AB  - A case of traumatic spinal subarachnoid hematoma causing compression of the cauda 
      equina is reported here. The patient, a 76 year-old woman, who had fallen down by 
      accident 1 month before, was admitted to our hospital presenting lumbar pain 
      radiating into her right thigh, monoplegia of the right leg and urinary 
      incontinence. Myelography and metrizamide CT demonstrated a filling defect 
      mimicking intradural extramedullary tumor at the level of L1 and L2. Magnetic 
      resonance imagings (MRI) revealed a subacute or chronic hematoma compressing the 
      conus medullaris and the cauda equina. Operation was performed and an old 
      hematoma, which occupied most of the spinal subarachnoid space and compressed the 
      conus and cauda equina from right to left, was removed. No definite bleeding 
      point was detected and no traumatic change was seen on the cord. Neither tumor 
      nor abnormal vessel was detected. After surgery, the symptoms improved partially. 
      On a review of the literature, we found only 4 cases of traumatic spinal 
      subarachnoid hematoma, all of which occupied the cervical or thoracic portion of 
      the spine. Our case is the first report, except for the cases following lumbar 
      spinal tap, of traumatic spinal subarachnoid hematoma causing compression of the 
      cauda equina. Though usually blood in CSF diffuses immediately, a clot may be 
      formed when a large amount of bleeding obstructs the spinal canal. In our case, 
      furthermore, deformity and narrowing of the spinal canal had preceded for many 
      years, following lumbar vertebral compressed fracture related with osteoporosis. 
      This might have promoted the process of canal obstruction and clot 
      formation.(ABSTRACT TRUNCATED AT 250 WORDS)
